1 Introduction 1.1 Product Overview The COM16155 is designed to provide quad-band GSM and GPRS with global positioning system (GPS) for PCI/104 based systems. Included on the COM16155 are a Cinterion MC55i-W quad band GSM cellular modem and a Linx RXM-GNSS-TM GPS Receiver module. The COM16155 has an ISA UART chip that permits communication with serial port on the GSM as well as the serial port on the GPS receiver module over the PCI/104 bus without using other serial ports in the PC/104 system.

When selecting a base address for the COM16155, please observe the following guidelines: Every device in your PC/104 system must have a unique base address! When selecting a base address for the COM16155, make certain that it does not conflict with any other devices. Base addresses 0x3F8 and 0x2F8 are typically used by serial ports COM1 and COM2, respectively. If you wish to use one of those base addresses, you will need to disable any conflicting serial port.
On when the SIM card is being powered from the cellular module D3 – 1 PPS Provides 1 PPS to LED, begins to flash once GPS has satellite fix. D4 – GSM STATUS Signal The GSM AT^SSYNC command serves to configure the STATUS pin of the application interface. The pin can either be used to indicate the current consumption in a transmit burst (default setting) or to drive a status LED connected to the pin. See the AT^SSYNC command for details.

3.4 Steps for Installing 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Always work at an ESD protected workstation, and wear a grounded wrist-strap. Turn off power to the PC/104 system or stack. Select and install stand-offs to properly position the module on the stack. Remove the module from its anti-static bag. Check that pins of the bus connector are properly positioned. Check the stacking order; make sure all of the busses used by the peripheral cards are connected to the cpuModule.
4 IDAN Connections 4.1 Module Handling Precautions To prevent damage due to Electrostatic Discharge (ESD), keep your module in its antistatic bag until you are ready to install it into your system. When removing it from the bag, hold the module by the aluminum enclosure, and do not touch the components or connectors. Handle the module in an antistatic environment, and use a grounded workbench for testing and handling of your hardware. 4.2 Physical Characteristics Weight: Approximately 0.21 Kg (0.

MC55i-W Module Interface The COM16155 GPRS/GSM modem is connected to the host computer through dedicated ISA serial port. The first serial port is connected to GSM ASC0. The default configuration for the GSM serial ports is: GSM Interface 9600 baud 8 data bits No parity 1 stop bit The modem can also connect through the USB interface. Simply load the USB driver and connect the USB to the USB port on your host computer.
A complete list of NMEA Messages and command messages is available from the manufacturer’s website at www.linxtechnologies.com. GPS module interface The RXM-GNSS-TM GPS is connected to the host computer through a dedicated ISA serial port. Carrier Detect of the serial port is driven by the 1 PPS signal.
6 Register Address Space This chapter shows you how to program and use your COM16155. It provides a general description of the I/O map. 6.1 General Board Control The memory map of the COM16155 occupies two groups of eight bytes of host PC I/O space. This window is freely selectable by the user by jumpers JP6 for GPS BASE and JP7 for the GSM BASE. After setting the base address you have access to the internal resources of the COM16155 control logic.
6.1.1 UART I/O (GPS/GSM BASE + 0 TO GPS/GSM BASE + 7) These are the UART registers for the GPS/GSM module. These resources are not described in detail, since they are mapped as a standard PC serial port. For more details on the EXAR 16C550 UART chip programming please download the component specific data from the website: http://www.exar.com. 6.1.2 GSM STATUS (GSM BASE +402H) BIT Bit 0 Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Bit 7 6.1.
6.1.5 DIGITAL I/O COM16155 allows bit programmable direction for all digital I/O bits. COM17045 compatibility is described later. Note the digital I/O registers are accessed at 404h – 407h above the GPS/GSM COM port. These addresses are used to interface to the digital I/O port. The 16 bits each have a direction bit. If the direction bit is set to output, a value written to the data bit is provided on the connector. A read will result in the value on the connector pin (i.e. the output value).

7 Troubleshooting If you are having problems with your system, please try the following initial steps: Simplify the System – Remove modules one at a time from your system to see if there is a specific module that is causing a problem. Perform you troubleshooting with the least number of modules in the system possible. Swap Components – Try replacing parts in the system one at a time with similar parts to determine if a part is faulty or if a type of part is configured incorrectly.
